摘要： A stabilized catalyst support having improved hydrothermal stability, catalyst made therefrom, and method for producing hydrocarbons from synthesis gas using said catalyst. The stabilized support is made by a method comprising treating a crystalline hydrous alumina precursor in contact with at least one structural stabilizer or compound thereof. The crystalline hydrous alumina precursor preferably includes an average crystallite size selected from an optimum range delimited by desired hydrothermal resistance and desired porosity. The crystalline hydrous alumina precursor preferably includes an alumina hydroxide, such as crystalline boehmite, crystalline bayerite, or a plurality thereof differing in average crystallite sizes by at least about 1 nm. The crystalline hydrous alumina precursor may be shaped before or after contact with the structural stabilizer or compound thereof. The treating includes calcining at 450° C. or more. Preferred structural stabilizers can include cobalt, magnesium, manganese, manganese, zirconium, boron, aluminum, barium, silicon, lanthanum, oxides thereof, or combinations thereof.

摘要： A catalyst and method for producing hydrocarbons using a catalyst support having an improved hydrothermal stability, such as under Fischer-Tropsch synthesis conditions. The stabilized support is made by a method comprising treating a boehmite material in contact with at least one structural stabilizer. Contacting the boehmite with at least one structural stabilizer can include forming a mixture comprising the boehmite material and at the least one structural stabilizer. The mixture can be a sol or a slurry. The treating preferably includes drying or spray drying the mixture, and calcining in an oxidizing atmosphere to obtain the stabilized support. Preferred structural stabilizers can include an element, such as cobalt, magnesium, zirconium, boron, aluminum, barium, silicon, lanthanum, oxides thereof, or combinations thereof; or can include precipitated oxides, such as a co-precipitated silica-alumina.

摘要： An LNG facility employing an enhanced nitrogen removal system that concentrates the amount of nitrogen in the feed stream to a nitrogen removal unit (NRU) to thereby increase the separation efficiency of the NRU. In one embodiment, the nitrogen removal system comprises a multistage separation vessel operable to separate nitrogen from a cooled natural gas stream. At least a portion of the resulting nitrogen-containing stream exiting the multistage separation vessel can be used as a refrigerant, processed to a nitrogen removal unit, and/or utilized as fuel gas for the LNG facility.
